LapRegec classification on 2-D data. In red and blue the labeled samples.


What is Laplacian Regec?   Learn more...
Supervised classification is one of the most powerful technique to analyze data, when a-priori information is available on the membership of data samples to classes. Unfortunately the labeling process can be both expensive and time-consuming. By exploiting the presence of unlabeled samples, semi-supervised algorithms can produce excellent classification models also when a small amount of labeled data is available. The LapRegec (Laplacian Regec) algorithm is a semi-supervised classifier obtained adding a Laplacian regularization term to Regec. LapRegec produces models that are both accurate and parsimonious in terms of labeled data samples.
